DOODLE

Free (iAps) Made for iPhone, iPad

It’s easy to send friends a text and ask if they want to meet for a party or some other event, but juggling everyone’s schedules can get complicated. Doodle does the work for you by allowing you to “poll” people to find out when they’re available. It compiles all the replies and tells you which dates work best. The free version has ads, but you can upgrade and ditch them for $43 per year.
